Title:
AQUEOUS COATING MATERIAL, CAN LID, AND BEVERAGE CAN
Document Type and Number:
Japanese Patent JP2022096728
Kind Code:
A
Abstract:
To provide an aqueous coating material favorably used for lid inner and outer face-coating capable of forming a coated film excellent in retort resistance even while using a surface active agent which is heretofore considered as a factor for reducing retort resistance, and capable of curing for a short time, capable of forming a coated film excellent in steam sterilization resistance, processability and adhesion.SOLUTION: An aqueous coating material includes: a polymer emulsion (D) obtained by polymerizing using 0.01-1 pts.mass of a nonionic water-soluble polymerization initiator (C) to 100 pts.mass of a mixture (A) of unsaturated ethylene monomers including a mono-functional (meth)acrylic acid ester-based monomer (A-1) having no carboxyl group, a monomer (A-2) having a carboxyl group, and an amide-based monomer (A-3) in the presence of water and a surface active agent (B); and a basic compound (E).SELECTED DRAWING: None
